Ice Packs – Ideal First Aid for Schools

Most instant ice packs contain a chemical solution that triggers an endothermic reaction, providing cooling relief for up to 30 minutes. In cooler environments, this reaction typically lasts longer, while in warmer conditions, the cooling effect may dissipate more quickly.

Instant hot packs typically provide heat for up to 40 minutes. As with cold packs, the exact duration can vary depending on factors such as the size of the pack, the surrounding temperature, and how well the pack is insulated during use. This time frame is generally sufficient for providing temporary relief from pain, muscle stiffness, or other discomforts.

Instant ice and hot packs can be safely transported via air travel, but specific rules apply depending on how they are packed. If you are traveling with instant ice packs as part of a personal first aid kit, it is recommended to pack them in your checked (hold) luggage. However, you may be allowed to carry them in your hand luggage if they are medically necessary. For example, if you need them to treat a medical condition, keep medication cool, or preserve food or drink for infants or special dietary needs, you can present the appropriate medical documentation to airport security.

For carry-on approval, instant ice/hot packs must comply with the airline’s liquid restrictions unless they qualify as medically necessary. Gel or liquid ice packs that are partially melted or slushy must also adhere to the 100 ml (3.4 oz) liquid rule unless exempt due to medical reasons. Always notify security officers if you are carrying these items for medical purposes, as their final decision will depend on the documentation you provide. Without proper justification, instant ice packs are typically not permitted in hand luggage.

Instant ice packs are designed for single use and should be disposed of safely after activation. As the name implies, they provide immediate cooling upon being activated. The endothermic reaction that occurs when the internal chemicals are combined typically lasts up to 30 minutes. However, once this reaction is finished, the pack cannot be reactivated or reused.

Instant ice packs have a limited shelf life due to the chemicals inside. When stored in a cool, dry place away from direct sunlight, they generally last for 18–24 months. It is recommended not to use instant ice packs beyond their expiration date and to dispose of them properly once expired.

Koolpak Instant Ice Packs are designed for single use, providing quick and effective cooling relief for injuries on the go. Once used, these disposable packs should be discarded according to local waste disposal guidelines, as they are not recyclable. It's important to keep both used and unused ice packs out of the reach of small children to prevent accidental exposure. 

When disposing of the pack, take care not to puncture the bag, as the liquid inside can create a mess if it leaks.
